AN ANNOUNCEMENT. 



Sharon, Wis. April 15, 1889. 



To OUR SUBSCRIBERS, 



This is to certify that 

 we hereby trausfer to Mr. Arthur E. 

 Pettit of New York the entire control 

 and good will of the Oologist's Exchange. 

 We regret the necessity of such a step 

 and would not make it were we not 

 satisfied of the greater ability of our 

 successor to please you. We are glad 

 to say (and must thank you) that the 

 Oologist's Exchange was a financial suc- 

 cess as long as we could do the work 

 ourselves but when the pressure of our 

 " closing out sale " deprived us of the 

 time and required us to engage an 

 assistant to attend to its publication we 

 deemed it more profitable to ourselves 

 as well as our subscribers to place it in 

 other hands. We thank you for your 

 assistance and support and hoping you 

 will continue the same to our successor 



we remain, 



Respectfully yours, 



Dickinson & Durkee. 



EDITORIAL. 



Every number after the present one, 

 will be issued on the 15th day of each 

 month. Subscribers who may, by some 

 mischance, fail to receive their paper, 

 please notify at once and paper will be 

 forwarded promptly. 



Querist must, in every case, inclose 

 stamp for reply, or question is liable 

 not to be answered. 



Subscription is twenty cents per year. 

 By sending thirty-five cents for a year's 

 subscription, one free exchange notice 

 will be allowed. 



We do not wish to start out like some 

 of our esteemed contemporaries, prom- 

 ising cash prizes, specimens worth 

 double price of subscription, etc., and 

 then fail to do half the things promised 

 and therefore offer no large inducements' 

 to subscribe. 



Articles of interest solicited from all. 



While our paper will be devoted 

 principally to Oology, we shall not 

 neglect the other branches of natural 

 history. 



Send in your articles and subscrip- 

 tions. Remember that a paper cannot 

 live on glory, but it needs plenty of 

 subscriptions, ads., etc., to keep it alive. 



Exchanges will please send two copies 

 as we always do the same. 



PRIZE STORY. 



For the most interesting collecting 

 experience, or an article giving the best 

 account of the habits, nesting or other- 

 wise, of any North American Bird, we 

 will give a pair of climbers strapped 

 ready for use. Eor the next best article 

 we will give a set of 1 egg No. 585, 

 American Flamingo. 



All articles sent in for competition 

 shall become the property of the paper, 

 and must not contain over 750 words. 

 All articles must be in by May 20. 



Now collectors, we have made you a 

 good offer ; show us that you appreciate 

 it, by giving us a hearty response. The 

 names of the prize winners, together 

 with their articles, will be published in 

 the "Oologist's Exchange." 



Oologist's Exchange, 



P. O. Box 2060, 



New York. 



There is an island on the coast of Cal- 

 ifornia, which is covered by three acres 

 of eggs. A sea captain who recently 

 visited it says the island is of rock with 

 a surface of about three acres. It is 

 covered with guano, in which sea fowls 

 of all descriptions were found laying or 

 incubating their eggs. The surface ap- 

 peared to be almost entirely covered 

 with eggs, principally those of sea-gulls, 

 shags and a small bird known as the 

 salt-water duck. He says it was difficult 

 to walk without treading on the eggs, 

 and a ship could be easily loaded with 

 them.
